ISO's main products are international standards. ISO also publishes technical reports, technical specifications, publicly available specifications, technical corrigenda, and guides.
International standards
These are designated using the format ISO[/IEC] [/ASTM] [IS] nnnnn[-p]:[yyyy] Title, where nnnnn is the number of the standard, p is an optional part number, yyyy is the year published, and Title describes the subject. IEC for International Electrotechnical Commission is included if the standard results from the work of ISO/IEC JTC1 (the ISO/IEC Joint Technical Committee). ASTM (American Society for Testing and Materials) is used for standards developed in cooperation with ASTM International. yyyy and IS are not used for an incomplete or unpublished standard and may under some circumstances be left off the title of a published work.
Technical reports
These are issued when a technical committee or subcommittee has collected data of a different kind from that normally published as an International Standard, such as references and explanations. The naming conventions for these are the same as for standards, except TR prepended instead of IS in the report's name.
For example:
ISO/IEC TR 17799:2000 Code of Practice for Information Security Management
ISO/TR 19033:2000 Technical product documentation Metadata for construction documentation
Technical and publicly available specifications
Technical specifications may be produced when "the subject in question is still under development or where for any other reason there is the future but not immediate possibility of an agreement to publish an International Standard". A publicly available specification is usually "an intermediate specification, published prior to the development of a full International Standard, or, in IEC may be a 'dual logo' publication published in collaboration with an external organization". By convention, both types of specification are named in a manner similar to the organization's technical reports.
For example:
ISO/TS 16952-1:2006 Technical product documentation Reference designation system Part 1: General application rules
ISO/PAS 11154:2006 Road vehicles Roof load carriers
Technical corrigenda
ISO also sometimes issues "technical corrigenda" (where "corrigenda" is the plural of corrigendum). These are amendments made to existing standards due to minor technical flaws, usability improvements, or limited-applicability extensions. They are generally issued with the expectation that the affected standard will be updated or withdrawn at its next scheduled review.
ISO guides
These are meta-standards covering "matters related to international standardization". They are named using the format "ISO[/IEC] Guide N:yyyy: Title".
For example:
ISO/IEC Guide 2:2004 Standardization and related activities General vocabulary
ISO/IEC Guide 65:1996 General requirements for bodies operating product certification
